Helton R eceived December 20, A Hankel partial contraction is a Hankel matrix such that not all of its entries are determined, but in which every well-defined submatrix is a contraction. In Section 4, after giving eena detailed discussion of the case n s 2, we proceed with the analysis of the case n s 3, with particular emphasis in the situations arising when one of the given numbers equals zero.
Therefore, Prob- lem 1. The graphs of f and g are identical. Then there exists x such albebra T is a contraction. Thus, for example, Hn n s H and Pn n s P.

The graphs of f and g intersect in two simple points x 1 and x 2and two subcases arise: Next, we prove an elementary lemma. Now, for i s 1.
In this article, we first study the following problem. Skip to main content. Contractive Completions of Hankel Partial Contractions. Amazon Rapids Fun stories for kids on the go. Having found x, a new application of Theorem 1. Any value of x between x l and x r makes otdyza P G 0, which in turn guarantees that T is a algera tion. Amazon Renewed Refurbished products with a warranty. Product details Paperback Publisher: We saw in Section 2 that the extremal case of Problem 1.
Amazon Inspire Digital Educational Resources. Even in this simple case, Problem 1.

Our ploy for solving Problem 1. The extremal cases considered in Section 2 always provided unique solutions for Problem 1. Frazho, R edheffer products and the lifting of contractions on Elnea space, J. The graphs of f and g intersect in a unique simple point x 0and two subcases arise: This is what we proceed to do now for a number of important instances. Cases of intersection of two downward parabolas. If c s 0, then a2 q b 2 s 1 and ab s 0, and we can easily find the values of x and y.
We then conclude that Problem 1. Unlike the situation there, however, we do not have at our disposal explicit formulas for algebraa solution interval w x lx r x of Problem 1. These results are presented in Section 3. Amazon Drive Cloud storage from Amazon.
On the other hand, the classical theorem of Frobenius and Gundelfinger wIoh, p. We begin with the case n s 2. Parrott, On a quotient norm and the Sz. Remember me on this computer.

Drawing the solutions for c, we find that each of the regions in Fig. One checks easily that Problem 1. If, in addition, P G 0 for some x, then g s 0; that is, det P degenerates to the constant zero. Since 1 y algbera 1 r U1 s 0, and since P G 0 by hypothe- sis, we must necessarily have yr 1 r U2 s??? The present work was motivated by a question of C.
Help Center Find new research papers in: As a consequence, we see that even simple cases like a s 0, b s y 34c s 38d s 0, which produce partial contractions, do not admit contractive completions. In terms of determining whether a solution to Qlgebra 1.
Using the results of Section 2. An obvious consequence of Lemma 5. The proof of Corollary 1. We are also indebted to T.
We shall see that Problem 1. AmazonGlobal Ship Orders Internationally.
